Catalog excerpts

Surface mount type PSD with 12 mm resistance length The S14241 is a one-dimensional PSD designed for precise distance measurement. It is a surface mount type PSD with a photosensitive area of 1 × 12 mm, and supports reflow mounting. Excellent position detectability Distance measurement High reliability Displacement meters Compatible with lead-free solder reflow Proximity switches Structure Parameter Photosensitive area Package Window material Resistance length Specification 1 × 12 Plastic Silicone resin 12 Absolute maximum ratings Parameter Reverse voltage Operating temperature Storage temperature Soldering conditions Symbol VR Topr Tstg - *1: When there is a temperature difference between a product and the surounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliablity. *2: See P.5. JEDEC J-STD-020 MSL 3 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.
